# The programmer who stopped programming

Boris Cherny built Claude Code. Now Claude Code builds Claude Code. After 30 days without opening an IDE, the future of software development looks very different.

There's a strange milestone in the history of software: the moment when the tool starts building itself. We may have just witnessed it.

Boris Cherny, who created Claude Code — Anthropic's AI coding assistant — revealed this week that he hasn't written a single line of code in 30 days. Every contribution to the project came from Claude Code itself, running on Opus 4.5.

"259 PRs. 497 commits. 40k lines added. 38k lines removed. First month I haven't opened an IDE at all. Sessions ran for hours, sometimes days."

The numbers are staggering, but the implications are what matter. If the creator of an AI coding tool no longer needs to code, what does that mean for the millions of developers using these tools?

The optimistic view: developers become architects and supervisors, focusing on design and review while AI handles implementation. The pessimistic view: we're watching the beginning of the end of programming as a profession.

The reality is probably somewhere in between — and we're all figuring it out together.

# SoftBank sells Nvidia to buy OpenAI

In a $40 billion bet on the future, Masa Son liquidated his entire Nvidia stake to become OpenAI's largest investor.

The deal closed this week: SoftBank has invested $40 billion in OpenAI, making it one of the largest private funding rounds in history. To make it happen, Masa Son sold his entire $5.8 billion position in Nvidia.

It's a fascinating strategic choice. Nvidia has been the clear winner of the AI hardware boom. But Son is betting that OpenAI's software and infrastructure play — specifically the Stargate project — will be even more valuable.

Sam Altman @sama

Excited to welcome SoftBank as our largest investor. The Stargate project will ensure America leads in AI infrastructure for decades to come.

SoftBank now owns approximately 11% of OpenAI. The money will fund Stargate, their joint venture focused on AI infrastructure. The thesis: whoever controls compute controls AI.

Whether this bet pays off depends on a lot of factors — regulation, competition from open source, and whether OpenAI can maintain its lead. But one thing is clear: the stakes have never been higher.
